IMPROVEMENT IN BOBBINS USED IN SPINNING MOHAIR, 800.

Specification forming part of Letters Patent No. 203,754, dated May 14,1878; application filed November 19, 1877.

To all whom it may concern:

Be it known that I, TOM MITCHELL, of Bradford, county of York, in theKingdom of Great Britain and. Ireland, have invented a new and usefulImprovement in Bobbins used in Spinning Mohair, &c., of which thefollowing is a specification:

The object of my invention is to prevent the fibers, near the top flangeof a bobbin, in spinning from becoming entangled and breaking the threadwhich is being spun and this object I accomplish in the manner which Iwill proceed to describe, reference being had to the accompanyingdrawing, in which Figure 1 is a side view of a spindle, flier, andbobbin of a spinning-machine with my improvement attached, and Fig. 2 asectional view of my improved cap for the bobbin.

In spinning mohair and other fibrous substances, the fibers close to thetop flange of the bobbin frequently become entangled, owing to thecentrifugal force, and break down, as the flier and bobbin revolve, thethread that is being spun.

In order to overcome this objection, I place on the top flange of thebobbin A a cap, B, of brass or any suitable metal, which projects ashort distance below the top flange of the bobbin, and which runs looseon the spindle G. This cap confines the fibers near the top of thebobbin, and prevents them from becoming entangled.

I do not desire to claim, broadly, a bobbin or spool with a cap on thetop flange of the same; but i I claim as my invention The combination ofthe spindle and bobbin with a cap adapted to fit over the upper flangeof said bobbin, and to project below the same, substantially as and forthe purpose herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

TOM MITCHELL. Witnesses:
